A bail hearing for South African sprinter Oscar Pistorius is happening this morning, and more details are coming to light about why the prosecutors do not buy his argument that he accidentally shot his girlfriend Reeva Steenkamp.

What's known is that on Valentine's Day, Pistorius shot his girlfriend through the bathroom door, killing her.

Prosecutors claim it was intentional, pre-meditated murder. His claim is that he thought there was an intruder coming into the house through the bathroom.

Among them: Witnesses heard a woman scream before all of the shots were fired, and Pistorius had to purposely angle the gun towards the toilet, something he wouldn't have done, apparently, if he really was thinking he was just firing at an intruder.
